Jesse Armstrong talks about the pressure of following the success of "Succession" with his new movie "Mountainhead."

Armstrong is still fascinated by the egotistical rich kids who hold our fates in their hands, but his latest project lacks the lightning-in-a-bottle chemistry that made "Succession" such a triumph.

Just like Succession, HBO's gone-but-not-forgotten drama series, Mountainhead comes from the satiric mind of Jesse Armstrong and focuses on a group of unserious billionaires. However, critics aren't as enthusiastic about the new TV movie as they were with its Emmy-winning predecessor.
